What is RNA-targeted therapeutics?

RNA-targeted therapies represent a platform for drug discovery involving chemically modified oligonucleotides, a wide range of cellular RNAs, and a novel target-binding motif, Watson-Crick base pairing. Numerous hurdles considered by many to be impassable have been overcome.

What does RNA therapy do?

An RNA therapy is designed to correct the mistake, or mutation, in the RNA of someone with a genetic disease. By correcting the mistake, the RNA can then be used to create the protein that the cell needs, taking away the underlying cause of the disease.

How is Crispr used in diagnostics?

CRISPR-based diagnostics have been used for a wide range of biomedical applications, and in particular for the sensing of nucleic-acid-based biomarkers of infectious and non-infectious diseases and for the detection of mutations and deletions indicative of genetic diseases.

Are there any approved mRNA therapies?

The Pfizer–BioNTech COVID-19 vaccine was the first mRNA vaccine approved by a medicines regulator, followed by the Moderna COVID-19 vaccine, and others. The main types of RNA therapeutics are those based on messenger RNA (mRNA), antisense RNA (asRNA), RNA interference (RNAi), and RNA aptamers.

How does RNA get into cells?

Through a process known as transcription, an RNA copy of a DNA sequence for creating a given protein is made. This copy – mRNA – travels from the nucleus of the cell to the part of the cell known as the cytoplasm, which houses ribosomes.

What are RNA drugs?

RNA therapies that target proteins use a type of molecule known as an RNA aptamer. Pegaptanib, a treatment for a form of age-related macular degeneration in which blood vessels penetrate the retina and cause vision to deteriorate, is an example of such a drug.

How long does it take RNA to degrade?

Their study revealed that commonly used methods provide distorted results and that RNA molecules live an average of only two minutes, ten times shorter than previously assumed. A research group at the Biozentrum, University of Basel, has developed a new method to measure the half-life of RNA molecules.

Is CRISPR a diagnostic tool?

CRISPR as a Diagnostic Tool. Using the principle that nucleic acids are effective biomarkers for diseases, CRISPR-based diagnostic methods rely primarily on identifying a certain sequence associated with a disease and then cleaving it in order to produce a readable signal.

How many RNA drugs are approved?

While only 3 small interfering RNA (siRNA)-based therapies have been approved, the market is poised to expand with 7 other candidates in phase 3 trials. While only 3 small interfering RNA (siRNA)-based therapies have been approved (patisiran, givosiran, and lumasiran), there are 7 other candidates in phase 3 trials.

Can RNA go back to nucleus?

In addition, some types of RNAs reenter to the nucleus after being exported to the cytoplasm [1]. Therefore, nucleo-cytoplasmic transport of RNAs and proteins is essential for eukaryotic gene expression. Among the various RNA species, mRNA is the most divergent in sequence, length, and structure.

How are RNA targeted therapies used in drug discovery?

RNA-targeted therapies represent a platform for drug discovery involving chemically modified oligonucleotides, a wide range of cellular RNAs, and a novel target-binding motif, Watson-Crick base pairing. Numerous hurdles considered by many to be impassable have been overcome. Today, four RNA-targeted … RNA-Targeted Therapeutics

What are the applications of RNA in medicine?

Recent advances in the generation, purification and cellular delivery of RNA have enabled development of RNA-based therapeutics for a broad array of applications. RNA therapeutics comprise a rapidly expanding category of drugs that will change the standard of care for many diseases and actualize personalized medicine.

Are there RNA-based diagnostic and therapeutic strategies for CVD?

The development of novel RNA-based therapeutic and diagnostic strategies that can target CVD is a multistep process (Fig. 1 ). In this Review, we discuss strategies to identify and validate new non-coding RNA molecules as targets for CVD therapeutics, focusing on preclinical studies performed in the past 10 years.

Why are RNA molecules a promising therapeutic candidate?

Given that RNA molecules have numerous roles in biological processes such as disease initiation and progression, RNAs have emerged as promising therapeutic candidates for many diseases 3. At present, protein-coding RNAs have been the most extensively studied, despite accounting for only a minority of all RNA molecules in the transcriptome.
